Scalpel Audio Editor 0.8.0
Scalpel is an audio editor for Linux written in Python. It aims at providing a simple-to-use and easy-to-extend audio editor. Sound hackers, get started translating your Matlab routines into Python/Numpy functions! Scalpel uses PyGTK for the user interface, Numpy for the internal processing, ALSA for the audio playing and libsndfile for reading and writing files. A minimal part of the code is written in Cython for better performance. Scalpel still has some rough edges but is quite usable. Try it now and be sure to send your feedback.

That's indeed a good idea, I will investigate it. But if this works, I still need some kind of wrapper around python itself... however, when I do the same on linux, python keeps looking for its dependencies in the build location. is there a possibility to have it always look at a position relative to the location of the executable ? the goal is to be able to build python on one machine, and then simply copy the build tree to other machines at other locations. Maybe looking at virtualenv, especially with the --no-site-packages variable set gives you a hint. AFAIK there are some hard-coded paths involved, but not inside compiled code.

A web site using Python
I would like to design a web site that can be used to help people to find a cat that they can adopt. Note, this is a non-profit project, but one that I believe to be quite important. Here are some of my initial thoughts on this project. /Site purpose:/ *To provide a web site for anyone to look at information on cats at this home, and how they can adopt one or more of these homeless cats.* /Some features of the site:/ 1. A cat database that I as the web site designer would create. This database would contain an entry for each cat available for adoption. It would include such things as the name, sex, age, paths to image(s) and/or video(s) of the cat, health status, etc (see below). 2. Anyone accessing this site should be able to easily navigate around it and to examine entries in this database. The client (designated person at the home where the cats are kept for adoption) would be given privileges to modify the database (add, delete, and modify entries). The user interface for the client to update the database should be very easy to use. This GUI provided to the client for modification of the database would be written in Python. 3. There would be no inputs to this web site. There would be an embedded link for a potential customer to send an email to the responsible person (bringing up their email client). 4. Track number of visitors to the site. /Preliminary notes on the database/ Fields: - ID code (key) - Name - Sex (M / F) - Neutered / Not neutered - Age (estimated) - Type (breed) - Tagged (chip or ear marking)/ Not tagged - Checked In date (yy/mm/dd) - Checked Out date (yy/mm/dd) - Status (needs home / has home) - Social state (1,2,3,4,5) - Health state (1,2,3,4,5) - Companion state (1,2,3,4,5) - Image (file name) % multiple files allowed - Video (file name) % multiple files allowed - Medical/vet data (text on vaccinations, etc.) - General information (text on cat that includes comments, observations, etc.) --- Notes on database: * state = 1, Best 5, Worst Examples: Social state = 5, very unfriendly, afraid, etc. 3, can touch if careful 1, very friendly, unafraid Health state = 5, not in good health (e.g. infection) 3, only minor health problems 1, in very good health Companion state = 5, must have another cat or cats as company 3, could be with other cat(s) company 1, does not need the company of another cat Now, with this initial information (granted this is very rough), my question: *How, armed with Python 2.6 (or 2.7) and all of the Python packages available, should I attack the problem of getting this web site up and running on a Windows platform?* Please keep in mind that do have some experience with Python and HTML; but, this would be my first web site project using Python.

Re: Print recent CGI error
I've sometimes got similar situations in CGI, that turned out to be because of a syntax error that kept apache from being able to run the script. What if you just run the script at the command line? It should either error out due to lack of a CGI environment/arguments, but hopefully it'll give you an error message that'll be useful. Also, you might be able to get some mileage out of finding out what env vars and command line options are being passed, and running from the command line with those.

The other problem is that no traceback seems to play well with a try-except block. I guess I am forced to use one or the other, but not both.

Which non SQL Database ?
Hello all. Newbie question. Sorry. As part of my process to learn python I am working on two personal applications. Both will do it fine with a simple structure of data stored in files. I now there are lot of databases around I can use but I would like to know yoor advice on what other options you would consider for the job (it is training so no pressure on performance). One application will run as a desktop one,under Windows, Linux, Macintosh, being able to update data, not much, not complex, not many records.

I'm assuming this is single-user (as in, each instance of your application has it's own DB) The second application, running behind web pages, will do the same, Is this multiple users, each accessing the same DB? That really changes what you are looking for. If you are dealing with single-user, or only a few users, I'd say look into SQLite - It uses SQL syntax but doesn't run as a server and stores the database as a single file. It's great to use in small projects because the syntax is the same as larger projects, and you can replace with a full-blown multi-user SQL DB if you ever need to without having to rework everything. It's also very simple to use. I believe SQLite (sqlite3) is part of the core library in recent Python versions, or available as a package for older pythons. Berkeley DB is pretty much interchangeable with SQLite in terms of functionality. I much prefer SQLite. If your web application intends to have multiple users interacting with the same data, neither is probably a good fit. -- Brett Ritter / SwiftOne swift...@swiftone.org -- http://mail.python.org/mailman/listinfo/python-list

Re: Comparison with False - something I don't understand
On 12/4/2010 12:07 PM, Harishankar wrote: Of course not. But going by the replies here, it appears that Python has made exceptions as the norm for error handling which is ironical considering the meaning of the word exception. In communications parlance, 'exception' = out-of-band signal or return value, while 'return'ed value = in-band signal. A fake in-band return value, like returning None (ok) or False (worse) to *signal* 'I cannot return a list' is still an exception signal, even if 'in-band'. The advantage of out-of-band signals is that they cannot be mistaken for valid in-band signals (return values). If a caller neglects to catch an exception, the process stops, as it should. If a caller neglects to check return values, the process goes on (at least for a while) under the pretense that error codes (in-band exception signals) are valid return values. Neglecting to check return values for error codes is a common bug in C code. At worst, the process eventually return a bad value or performs a bad action. At best, it crashes sometime later, making the bug hard to find. Or a function is called without even storing, let alone checking the return value. This is common for i/o functions. A program may 'finish' without any indication that it failed. If one does the same with Python functions (equally common), any exceptions *will* be passed up until either caught or displayed on the screen with an informative traceback (assuming that the screen is the not source of the error). -- Terry Jan Reedy -- http://mail.python.org/mailman/listinfo/python-list

Whether you happen to like the exception mechanism and syntax or not, it is the idiomatic way of handling errors in Python. Using two different conventions in your code will lead to confusion. I come from a long C background as well. I have come to appreciate the power the Python's exception handling provides. It does everything that you need to do with passing values in C and more. The issue to be considered by every programmer is to define what can be defined as the exceptional condition and what is a condition that merits merely different treatment without causing disruption of the normal flow of the program. That is an issue much harder to define. Anything it is an obvious error *should* throw an exception. Invalid input is an error. Unusable hardware states are errors. Any invalid request to an object, is an error. Essentially anything that deviates from a normal flow of a program, to handle an exceptional condition, is an error Where it becomes less obvious is when you start using exceptions as part normal control flow. An example is a try it and see methodology. You might for instance have a group of file objects which might or might not support a particular method attribute. You might have a preference for using the attribute; but, have a fallback plan if it does not. One way to handle this is to try to use the attribute and catch the exception raised if it is not present to execute your backup method. I have found this *essential* in some marsaling enviroments where you might not have access to the meta-data of the object that you are working with. Another, questionable but useful use, is to ignore the complex accounting of your position inside of a complex data structure. You can continue moving through the structure until an exception is raised indicating that you have reached a boundary of the structure. Whether you accept uses of exceptions like these is more of a personal quesion. Like many good tools, they can be useful in ways that they were never really designed to be and I would hate to proclude some of these really useful features. This can, of course, be easily abused. I was once writing code, involving complex object marshaling like I described above, with a partner who wasn't totally familiar with Python. We came to a situation where it was impossible to know ahead of time what kind of object (one of two possiblities) we would receive from another marshalled object and had no meta-data to be able to figure out before attempting to access the object. I used a try/except clause to resolve the problem. The next day, I found several poorly conceived try/except blocks in the codebase that my partner had used for control structures using dictionaries because he didn't know of dict.has_key(). I was not so pleased. -- http://mail.python.org/mailman/listinfo/python-list

Then I would call reset() on the first dice and increment the second and so on much like the odometer of a car. By using exceptions rather then checking the return value of increment, the state information of the dice was completely isolated to the dice and did not polute into the role structure; the logic for incrementing the dice, logging the role state, and rolling over the dice where all completely seperated and independent of any state; and therefore reseting multiple previous dice as the higher values on the odometer were incremented functioned automatically as each dice threw its own exception recursively rather then requiring logic to handle these multiple rollovers. -- http://mail.python.org/mailman/listinfo/python-list

E.g. str.find, or the use of quiet NANs in IEEE floating point and decimal maths. NANs and INFs in floating point maths are a good example of the right way to do it. If you forget to check for a NAN, it will propagate through your calculation. INF will, under some circumstances where it is mathematically valid to do so, will disappear leaving a normal result. This means you only need to check your result at the very end of the calculation, not after every step. str.find is more troublesome, because the sentinel -1 doesn't propagate and is a common source of errors: result = string[string.find(delim):] will return a plausible-looking but incorrect result if delim is missing from string. But the convenience and familiarity of str.find means it will probably be around forever. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

Working that out for himeself was probably far more educational then simply reading an article on the solution.

I basically created a DSL that he could use to generate and automatically calculate the properties of series of roles defined by one or more varying property. I merely posted a simplied description of the dice-role objects because I thought that it demonstrated how exceptions can provide eligance of control for situations that don't involve what would traditionally be defined as an error. -- http://mail.python.org/mailman/listinfo/python-list

I'll leave it open for a while to allow others to comment. I have some sympathy for the idea: I also think that the str/repr of a complex number would look better with spaces (and without parentheses (and with 'i' in place of 'j'))). I've always appreciated the fact that lists are printed in the form '[1, 2, 3]' rather than the less readable '[1,2,3]'. But there's a big difference between 'it might have been better if ...' and 'it's worth changing this'. Tinkering with minor details like this from release to release just isn't worth the potential difficulties (however minor) caused to users as they have to adapt their code.

Eli Bendersky eli...@gmail.com added the comment: Attaching a patch with the following: 1. list.copy() and list.clear() implemented in Objects/listobject.c, with appropriate doc strings (modeled after dict's docstrings) 2.

[issue10516] Add list.clear() and list.copy()
Éric Araujo mer...@netwok.org added the comment: Hi Eli, I think the right place is 4.6.4, http://docs.python.org/dev/library/stdtypes#mutable-sequence-types It starts with “List and bytearray objects support additional operations that allow in-place modification of the object”. For methods not supported by bytearray, you can use the fake footnote (8) and edit its texte (“sort() is not supported by bytearray objects”).

[issue10609] dbm documentation example doesn't work (iteritems())
Éric Araujo mer...@netwok.org added the comment: Arg, the internal classes returned by dbm.*.open have keys but not necessarily items. See #9523, #6045 and #5736. The docs should be fixed independently of that, with the less non-idiomatic code that we can find. Do you want to check the dbm docs for other similar broken examples? I’ll review the patch. -- assignee: d...@python - eric.araujo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10609 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7936] sys.argv contains only scriptname
Jiri Kulik jiri.ku...@jkulik.eu added the comment: Encountered the same issue with 3.1.2 and 3.1.3 64bit on Win7 64bit. I was able to fix it in registry but did so many changes at once that I'm not able to reproduce (was really annoyed after trying to fix it for half a day...). Anyway, sending my observations: - the root cause seems to be creation of python.exe and pythonw.exe entries under HKEY_CLASSES_ROOT. Their open command did not have %*. They were not created under HKEY_LOCAL_MACHINE. They were probably created automatically by the system when manually associating py and pyw files (see below). - .py and .pyw files were originally associated with py_auto_file and pyw_auto_file in HKCR. The associations were probably created by the system, when I manually change association of the .py and .pyw files from jython to python through control panel. The py_auto_file and pyw_auto_files seemed to call those python.exe and pythonw.exe entries in the HKLC. - The assoc and ftype commands changed association in HKLM but it is not propagated automatically into HKCR, not even after restart. After manually deleting .py and .pyw entries from HKCR, they were replaced by correct entries from HKLM. - BUT!! the system still called open commands under python.exe and pythonw.exe entries in HKCR! (even if .py was associated with Python.File in HKCR and proper Python.File existed even in HKCR!) Only after deleting them, it works as should. But I deleted a lot of other python related entries as well, so this is only assumption. If anyone else can confirm that deleting of python.exe and pythonw.exe from HKCR itself corrects the issue, I think the installation program can check if these entries exists and offer to delete them. Just for complete picture, it works now even with .py and .pyw in PATHEXT, so calling the scripts without extension. -- nosy: +jiri.kulik versions: +Python 3.3 -Python 3.1 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7936 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
